 /**

 MDrawDeviceOrigin interface manages the origin point of CFbsDrawDevice interface.

 The interface could be retrieved calling CFbsDrawDevice::GetInterface() with 

 KDrawDeviceOriginInterfaceID as an argument.

 If the drawing device does not have support for moving origin, MDrawDeviceOrigin cannot be retrieved.

 MDrawDeviceOrigin interface lifetime is the same as the lifetime of CFbsDrawDevice

 interface, which creates it. 

 Do not try to delete MDrawDeviceOrigin interface pointer!

 MDrawDeviceOrigin interface offers following methods: 

 Get(), Set().
